c423bc8509 drm/omap: check that plane is inside crtc
DRM allows planes to be partially off-screen, but DSS hardware does not.
This patch adds the necessary check to reject plane configs if the plane
is not fully inside the crtc.

794a65ffba drm: omapdrm: if omap_plane_atomic_update fails, disable plane
omap_plane_atomic_update() calls dispc_ovl_setup(), which can fail (but
shouldn't). To make the code a bit more robust, make sure the plane gets
disabled if dispc_ovl_setup() fails, as otherwise we might get illegal
HW configuration leading to error interrupts.

11ffd031e3 drm: omapdrm: inline omap_plane_setup into update/disable
At the moment we have omap_plane_setup() function which handles both
enabling (and configuring) and disabling the plane. With atomic
modesetting we have separate hooks for plane enable/config and disable.

This patch moves the code from omap_plane_setup() to
omap_plane_atomic_update() and omap_plane_atomic_disable().

d9157dfd04 drm: omapdrm: omap_plane_setup() cannot fail, use WARN
With atomic modesetting, omap_plane_setup()'s return value is ignored as
the functions using it cannot fail. dispc_ovl_setup(), called by
omap_plane_setup(), can fail (but shouldn't).

Instead of returning an error from omap_plane_setup() which gets
ignored, return void and use WARN if dispc_ovl_setup() fails.

edc725577c drm: omapdrm: Remove omap_plane enabled field
The field tracks the plane state to avoid double-enable or -disable.
This isn't required anymore, as

- the DRM atomic core guarantees that the plane atomic_update and
  atomic_disable functions will never be called on an enabled/disabled
  plane

- the CRTC enable/disable operations that enable/disable the plane are
  already guarded against double enable/disable

We can thus remove the enabled field completely. The
omap_plane_set_enable() function then becomes a wrapper around
omap_plane_setup() which can be called directly.

afc3493243 drm: omapdrm: Switch crtc and plane set_property to atomic helpers
Allow setting up plane properties atomically using the plane
set_property atomic helper. The properties are now stored in the plane

a42133a780 drm: omapdrm: Apply settings synchronously
The omapdrm driver implements a mechanism to apply new settings (due to
plane update, plane disable, plane property set, CRTC mode set or CRTC
DPMS) asynchronously. While this improves performance, it adds a level
of complexity that makes transition to the atomic update API close to
impossible. Furthermore the atomic update API requires part of the apply
operations to be synchronous (such as pinning the framebuffers), so the
current implementation needs to be changed.

Simplify the CRTC and plane code by making updates synchronous to
prepare for the switch to the atomic update API. Asynchronous update
will be implemented in a second step.

f2d022aa42 drm/omap: fix the handling of fb ref counts
With the recent primary-plane changes for drm, the primary plane's
framebuffer needs to be ref counted the same way as for
non-primary-planes. This was not done by the omapdrm driver, which
caused the ref count to drop to 0 too early, causing problems.

This patch moves the fb unref and ref from omap_plane_update to
omap_plane_mode_set. This way the fb refs are updated for both primary
and non-primary cases, as omap_plane_update calls omap_plane_mode_set.

b03e14fd4b drm/omap: Take a fb reference in omap_plane_update()
When userspace calls SET_PLANE ioctl, drm core takes a reference of the fb and
passes control to the update_plane op defined by the drm driver.

In omapdrm, we have a worker thread which queues framebuffers objects received
from update_plane and displays them at the appropriate time.

It is possible that the framebuffer is destoryed by userspace between the time
of calling the ioctl and apply-worker being scheduled. If this happens, the
apply-worker holds a pointer to a framebuffer which is already destroyed.

Take an extra refernece/unreference of the fb in omap_plane_update() to prevent
this from happening. A reference is taken of the fb passed to update_plane(),
the previous framebuffer (held by plane->fb) is unreferenced. This will prevent
drm from destroying the framebuffer till the time it's unreferenced by the
apply-worker.

This is in addition to the exisitng reference/unreference in update_pin(),
which is taken for the scanout of the plane's current framebuffer, and an
unreference the previous framebuffer.
